Have a 03 F250 no mods 201k on odometer, had a stall or miss when it shifted into o/d...then this morning it was a bit cold out but truck cranked fine pulled out of driveway and a couple blocks down it started sputtering and wanted to die but made it a few more blocks and it finally died...it will turn over but won't start and acts like it wants to start but just sputters checked ficm got 47.8V, fuel coming into filter but after I started trying to solve the problem found that coolant was low so i topped it off but when I did some milky foamy white stuff came up??? No water in oil that I can tell so far so i am puzzled... What can be goin on??? Head gaskets? Blown oil cooler? Please help anybody...I an new to this forum but I always look into your threads for advice...

No codes, not sure on the smell, foamy white stuff in coolant res. at first i thought it could be a fuel issue like the FICM or ICP sensor but the FICM checked out ok when I was goin to check ICP for oil in pigtail I noticed the low coolant and when I topped it off I noticed the foamy white residue so I assume the worst...It turns over but it sounds like it wants to turn on for a second but it doesn't. Another thing a friend of mine climbed up on top and saw residue under the turbo towards the firewall and it seemed like oil by sight but smelled like fuel don't really know whats goin on...Another thing I noticed was the bottom of the bell housing was dry before now has oil on one side and saturated on bottom thays why I thought the ICP could be bad...

I know its a PITA, but try reaching back there and unplugging the ICP. Most times when they do go bad, they start to leak oil all over the place, and the joy of the 03's is that the ICP is under the turbo in front of the IPR. By unplugging it, if its bad, it sets a default pressure and the truck should start.

Ok I will try that but I checked the degas bottle and the white foamy stuff smelled like engine oil not fuel, that is not normal is it? I haven't had my truck long so a friend suggested a coolant filter and blue spring upgrade kit which I already done both... When i got the truck there was no residue in the degas bottle, will the bad ICP allow oil into coolant? Any help or advise will be greatly appreciated.

Engine oil in the coolant most likely means a ruptured oil cooler. I don't have any experience with this happening but I would imagine your gonna have coolant in your oil too. If you've got coolant in your oil then the HPO system is definitely not gonna work right. I have never liked the idea of fluids being separated by thin metals hence the reason I went with bulletproof's oil cooler, and also why I bypassed the radiator trans cooler on my wife's nissan and just use the external cooler.
